Simplify the polynomial expressions by combining like terms, and then multiply the resulting binomial expressions to find their

Lesechka [4]

For this case we have the following expression:
$(8x - 9 - 2x) (15 + 5x - 5)
$
The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:
$(6x - 9) (5x + 10)
$
Then, doing distributive property we have:
$30x ^ 2 + 60x - 45x - 90
$
Adding similar terms:
$30x ^ 2 + 15x - 90$
Answer:
The simplified expression is:
$30x ^ 2 + 15x - 90$

What Is The Recursive Rule For The Sequence? 1.2, 0.4, -0.4, – 1.2, -2,

nevsk [136]

<h3>Answer:</h3>

$\boxed{\bold{a_n = a_{n-1} -0.8}}$

<h3>Explanation:</h3>

<u>Sequence</u>: 1.2, 0.4, -0.4, – 1.2, -2,...

See that with every next term, the integers are decreasing by 0.8

So, common difference (d) = -0.8

<u>recursive formula</u> : $\sf a_n = a_{n-1} +d$

$\bold a_1 = 1.2,$ $\sf a_n = a_{n-1} + (-0.8)$

Combine like terms and apply the distributive property to create an equivalent expression:

chubhunter [2.5K]

Answer:

Equivalent expression is $15a+8b$

Step-by-step explanation:

Given expression is,

$2\left(5a+3b\right)+5a+2b$

First step is to apply distributive property. The property states that,

$a\left(b+c\right)=ab+ac$

Applying the property,

$2\left(5a\right)+2\left(3b\right)+5a+2b$

Simplifying,

$10a+6b+5a+2b$

Collecting like terms,

$10a+5a+6b+2b$

Combining the like terms,

$15a+8b$

Therefore, equivalent expression is $2\left(5a+3b\right)+5a+2b=15a+8b$
